Patent DE-3147985-A1 (DE)
Inventor: BAYER ERICH
IPC: G02B5/20
Filed: 1981-12-04
Abstract: A recording medium with a multicolor high resolution pattern created by layer packs. Pattern-forming layers of the layer packs are successively applied by photolithographic means in a sequence corresponding to a color of the high resolution pattern. The pattern-forming layers of the layer packs are separate from one another on the substrate of the recording medium. The process for producing the recording medium includes applying a photoresist layer to a substrate and developing the photoresist. Pattern-forming layers are successively applied over the whole surface of the substrate in a sequence corresponding to a color. The remaining photoresist and the layers overlying it are removed to leave a sequence of pattern-forming layers on the substrate separate from any adjacent pattern-forming layers.

Title: Process for preventing or reducing stress corrosion cracking
Inventor: KRAUSS HELMUTH DIPL ING
IPC: C23F11/10
Filed: 1982-02-20
Abstract: Process for preventing or reducing stress corrosion cracking on workpieces and/or components of rust- and acid-resisting, austenitic and ferritic-austenitic steels, which are exposed to the action of an aqueous attacking medium containing dissolved chloride. The desired prevention or reduction of the occurrence of stress corrosion cracking in such workpieces is achieved by adding at least one ionic surfactant to the attacking medium. Surfactants added to the attacking medium in a quantity of 0.05 to 1.0 g/l, and in particular both anionic and cationic surfactants, effect a complete prevention or extensive reduction of the formation of stress cracks, as a function of the parameters which promote stress corrosion cracking.

Title: Tear-open lid
Inventor: KOHLMEIER WILFRIED
IPC: B65D17/32
Filed: 1982-02-27
Abstract: The present tear-open lid has in the lid surface or lid plate (1) an elongate orifice (3) which has parallel side edges (2a, 2b) and in which a closing element (10) is embedded. The closing element (10) has a circumferential groove (14) matched to the shape of the orifice (3). This circumferential groove is formed by a flange (15) and, after the initial opening, allows the closing element (10) to slide along the parallel side edges (2a, 2b). The closing element (10) is equipped with a stop (21), so that the sliding travel is limited and the closing element (10) remains on the lid even after opening. Arranged round the end (5) of the orifice (3) facing the gripping part (19) of the closing element (10) is a scoring line (6) which, together with the edge of the end (5), describes a surface part (26) which, after the first opening, is also torn out of the lid plate (1) and remains constantly on the closing element (10) for the purpose of protecting the environment. After the surface part (26) has been torn out, the lid plate (1) has a good passage for the flange (15) of the closing element (10). For reclosing, the closing element (10) is pushed back, the surface part (26) making close contact again with the lid plate. <IMAGE>
Patent DE-3219668-A1 (DE)
Title: Circuit for activating the light-emitting diode of an optocoupler
Inventor: KIRSCH RAINER DR ING
IPC: H04B10/80
Filed: 1982-05-26
Abstract: The invention describes a circuit for activating the light-emitting diode of an optocoupler in which, according to the invention, two amplifier stages are provided, of which the first amplifier stage generates a current below a threshold value of the input voltage, which current does not flow through the light-emitting diode. Once the threshold value has been exceeded, the second amplification stage then receives the current which then flows through the light-emitting diode. The threshold value can be selected independently from the response voltage of the light-emitting diode. Manufacturing tolerances and temperature influences are thereby eliminated as interference quantities. Since no current flows through the light-emitting diode below the threshold value, the optocoupler is immune to capacitively and inductively produced interfering voltages up to the level of this threshold value. Furthermore, this circuit draws the auxiliary power required for the amplifiers from the input signal so that no additional lines are required for the auxiliary power supply.
Patent DE-3222158-A1 (DE)
Title: Circuit arrangement for generating small programmable time intervals
Inventor: BUTTENSCHOEN PETER
IPC: G04F1/00
Filed: 1982-06-12
Abstract: In this arrangement, a reference generator and a vernier generator generate pulse sequences which differ by the smallest switchable time interval. Two counters, which can be programmed by a program generator, are started by a clock signal of a frequency divider following the reference generator and are in each case controlled to count down by the clock signals of the reference generator or of the vernier generator, respectively. These counters determine the respective time interval by means of the difference between their output signals.

Patent DE-3307338-A1 (DE)
Title: Coffee maker
Inventor: BERGFELD HELMUT
IPC: A47J31/06
Filed: 1983-03-02
Abstract: For a coffee maker with a filter, a coffee jug and a resting surface as well as a closure which prevents dripping from the drainage opening of the filter, a lock is proposed which does not allow the coffee jug to be removed when the closure is open. For this purpose, a rotatable adaptor on the filter, which serves for actuating the closure, has an insertion opening for the lid of the coffee jug, as a result of which, in conjunction with an approximately semi-circular collar of the resting surface, it is ensured that the coffee jug can be placed in the coffee machine or removed therefrom only at a particular angular position of the adaptor. A further improvement is achieved in that the adaptor is actuated indirectly by rotating the coffee jug. For this purpose, the lid is placed on the coffee jug so as to be fixed against rotation and the insertion opening and the insertion part of the lid are constructed to transmit a torque. <IMAGE>

Title: Method and device for retaining contaminated water clear of a receiving water course
Inventor: STAHN ROLF
IPC: E03F5/10
Filed: 1983-09-22
Abstract: Especially in the sector of municipal waste water management, a problem exists with the emergency disposal of waste water into receiving water courses as a result of the water contamination entailed. It is known that retention tanks are built to solve this problem. In densely populated urban areas, however, further problems and very high expenditures are caused by the question of location of retaining tanks with a favourable disposition relative to a waste water drain without lengthy additional connecting pipes, possible acquisition of land and the need to site the tanks underground. It is therefore a logical idea to arrange retention tanks of a particular structure in the receiving water course itself or as close as possible to it, directly connected to existing emergency disposal points from mixed-water drains into a receiving water course. Such a retention tank has been described. It differs fundamentally from the conventional tanks in its manner of operation, since it is not emptied or filled in the conventional sense but is always full of water, filling and emptying taking place by a reciprocal exchange of waste water and water from the receiving water course. This tank is naturally open on one side and thus corresponds to the level of the receiving water course. In order to obtain a defined interchange of water, an essential built-in component of this tank is a hydraulically movable wall which rests on the edges of the tank and is automatically driven. A further advantage resides in the fact that ... Original abstract incomplete.
